What is a network in SAP Project System? A network can represent the sequence of activities in a project or the sequence of a single activity in a project. Project Manager can graphically display assorted structural elements of a project and their interdependencies in the Project System. During the life of a project, networks are use as basis for planning, analyzing, controlling, and monitoring schedules, dates, and resources.

Some types of questions can be answered with the information that can be obtained from a network, as follows:

• Where are the scheduling uncertainties and how significant are they?
• Where are we not clear on the processes in the project and what are the possible consequences?
• When and in what quantity do resources have to be available so that we can keep to the schedule?
• When and in what amount do we incur costs and make expenditures for the project?

Networks in the Project System are activity-on-mode networks. Networks have two essential components: 1). Activities, and; 2). Relationships between the activities.
